Product details
Overview
BZD27C150PH from Taiwan Semiconductor is a 1 W, 147 V nominal zener diode in Sub SMA package, rated for 150 V Zener voltage (138–156 V range), 5 mA test current, and 175 °C max junction temperature; it delivers stable voltage regulation in automotive-grade DC/DC converters and industrial power supplies.
For engineers reviewing the BZD27C150PH datasheet, BZD27C150PH pinout, BZD27C150PH application, or BZD27C150PH equivalent, key selection criteria include its AEC-Q101 qualification, 150 Ω dynamic resistance at IZ, 0.09 %/°C temperature coefficient, and 100 W non-repetitive peak pulse power rating for surge immunity in harsh environments.
Technical Context
The BZD27C150PH operates as a single-die, surface-mount silicon zener diode optimized for precision voltage clamping and regulation under transient overvoltage conditions. Its design supports stable reverse-biased operation with low leakage (≤1 μA at 110 V) and tight VZ tolerance (±5 % at 147 V).
Thermal performance is defined by RθJA = 88 °C/W on a 5 mm × 5 mm Cu pad, enabling reliable power dissipation up to 1 W at 25 °C ambient and 2.3 W at 73 °C lead temperature. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity.

FAQ
What is the Zener voltage tolerance of BZD27C150PH?
The BZD27C150PH has a Zener voltage range of 138 V to 156 V at 5 mA test current, corresponding to a ±5 % tolerance around the nominal 147 V value. This tight tolerance is specified per the manufacturer's electrical characteristics table and ensures predictable clamping behavior in precision regulation circuits where BZD27C150PH is deployed.
Is BZD27C150PH suitable for automotive applications?
Yes, BZD27C150PH is AEC-Q101 qualified and rated for junction temperatures up to 175 °C, making it suitable for under-hood automotive applications such as on-board DC/DC converters and engine control module power rails. Its qualification covers stress testing for temperature cycling, humidity, and mechanical shock-key requirements verified for BZD27C150PH in production lots.
What is the maximum non-repetitive peak pulse power for BZD27C150PH?
The BZD27C150PH supports 100 W non-repetitive peak pulse power for a 10/1000 μs waveform, as specified for devices from BZD27C110PH through BZD27C220PH. This rating applies to transient surge events like load dump or EFT, and is validated under TJ = 25 °C prior to surge-critical for BZD27C150PH deployment in ISO 7637-2-compliant systems.
Does BZD27C150PH have halogen-free and RoHS-compliant construction?
Yes, BZD27C150PH uses halogen-free molding compound per IEC 61249-2-21 and is fully RoHS compliant. These environmental specifications are explicitly stated in the product features section and confirmed in the mechanical data sheet revision A2103-ensuring BZD27C150PH meets global regulatory requirements for sustainable electronics manufacturing and end-of-life processing.
What is the thermal resistance from junction to ambient for BZD27C150PH?
The junction-to-ambient thermal resistance (RθJA) of BZD27C150PH is 88 °C/W when mounted on a standard 5 mm × 5 mm copper pad, as measured per JEDEC test conditions. This value directly governs the allowable power dissipation at elevated ambient temperatures and is essential for thermal design validation when using BZD27C150PH in enclosed or high-temperature enclosures.
